The defender was a free agent after his contract with AS Roma expired.
âI keep all the Roma teammates in my heart, as Iâll never forget the city and its fans, who did so much for me. Now I am at Milan and very proud to be part of this club,â he said.
âI had seven marvellous years at Roma and itâs partly thanks to them that I grew as a man and a player to earn this opportunity with Milan.
âIt was my choice, as I couldâve joined Real Madrid this summer. In the past I chose Roma ahead of Manchester United. I dreamed of a club like this since childhood and itâs an important shop window, so I can hope to earn a place in the France squad for Euro 2012.â
